Problem:
Trying to use the

wpml_switch_language

function within a filter to list posts from the default language on a page translated to another language, and can't get the

wpml_switch_language

to work.

Solution:
Firstly, it's important to note that the

wpml_switch_language

action hook must be used with the

pre_get_posts

WordPress hook. This means that you should integrate the language switch into the query modification process. Here's how you can do it:

1. Use the

pre_get_posts

hook to modify the query before it runs.
2. Inside your hooked function, call

do_action('wpml_switch_language', 'all')

to switch the language.
3. Then set up your query arguments and run the query.

For more details and usage examples, you can refer to the following documentation:

• WPML switch language hook
• WordPress pre_get_posts hook

Additionally, there are alternative approaches you can consider, such as:
